getchaintips

getchaintips Return information about all known tips in the block tree, including the main chain as well as orphaned branches.

Result: [ { “height”: xxxx, (numeric) height of the chain tip “hash”: “xxxx”, (string) block hash of the tip “branchlen”: 0 (numeric) zero for main chain “status”: “active” (string) “active” for the main chain }, { “height”: xxxx, “hash”: “xxxx”, “branchlen”: 1 (numeric) length of branch connecting the tip to the main chain “status”: “xxxx” (string) status of the chain (active, valid-fork, valid-headers, headers-only, invalid) } ] Possible values for status:

“invalid” This branch contains at least one invalid block
“headers-only” Not all blocks for this branch are available, but the headers are valid
“valid-headers” All blocks are available for this branch, but they were never fully validated
“valid-fork” This branch is not part of the active chain, but is fully validated
“active” This is the tip of the active main chain, which is certainly valid
